- Do not use the airbag system and pretensioners on other vehicles. When replacing parts, be sure to replace them with new parts.
- When checking the airbag system, be sure to use a digital circuit tester. Use of an analog circuit tester may cause the airbag to activate erroneously due to a minimal current inside tester.

- Do not discard undeployed airbag module. They could easily cause a serious accident if accidentally deployed.
- When storing a removed airbag module, do not place it with the pad side facing downward. Do not place any objects on the airbag module. Do not pile airbag modules on top of each other. If the airbag inflates for some reason when an airbag module pad is touching other objects, it may cause serious accident.
